HOLDIDOWN FOR LASTING-MACHINES.

Specification of Letters Patent.

Patented Mar. 13, 191?.

7 Application filed May 26, 1913. Serial No. 769,954.

To all whom it may concern:

Be it known that I, Lnwis H. LARSEN, a citizen of the United States,residing at Racine, in the county of Racine and State of lVisconsin,have invented certain improve ments in Holddowns for Lasting-Machines,of which the following description, in connection with the accompanyingdrawings, is a specification, like reference characters on the drawingsindicating like parts in the several figures.

This invention relates to lasting machines and particularly to means forholding the work in bed lasting machines.

In lasting shoes upon the commercial bed lasting machines, it isnecessary that the shoe be held down firmly upon the toe rest and it isimportant that the innersole be firmly held at and adjacen't to thechannel lip at and around the end of the toe because while the upper isbeing wiped over the edge of the last and over the feather of theinnersole the innersole tends to crumple up at the channel or the ribline, or even to be displaced bodily unless it is securely held againstsuch action. The difficulty from crumpling of the innersole hasseriously increased within the past few years during which the greatadvance in the price of leather has obliged manufacturers, in order tohop as near as possible to the former nmnufacturing cost, to use athinner innersole or one which is of less firm quality, it having beenfound that such an innersolr will give good satisfaction provided theshoe is properly lasted and welted.

In addition to the difficulties arising from the crumpling up of theinnersole at the channel and the consequent displacement of the lipwhich determines the stitching line by which the welt is attached aroundthe toe, the use of these thinner and more flexible innersoles greatlyincreases, as would be expected, the liability that the lip or rib willbe bent inwardly or overridden in lasting the toe of the shoe so thatthe upper materials lie upon it and render uncertain or impossible theproper stitching of the upper materials and welt to it. This diflicultyis increased by the present use of bulky fabric toe stiffening materialin place of the thinner but more expensive sole leather stiffeners.

For these reasons it has become increasingly important to provide acontinuous support or abutment for the inner face of the channel lip atthe tip of the toe and in order to serve its purpose adequately thissupport or abutment must extend backwardly a considerable distance onone or both sides of the toe but particularly on the outer side of thetoe Where is found the swing that characterizes distinctively right andleft lasts. The best results in lasting toes are obtained, as I havefound, by the use of a continuous or substantially uninterruptedabutment for the inner face of the channel lip around the toe, saidabutment having an edge contour to lit the innersole accurately insidethe lip and constituting in eflect an inside former between which andthe lasting plates as outside formers the upper and stiffener materialsare molded and compressed into an upstanding flange against the channellip. By so lasting the toe it is easy to sew it in the welting operationand, moreover, the inseam or line of attachment of the welt isaccurately located where the designer of the shoe intended it should beand the appearance of the shoe is not adversely affected by a distortedinseam at the toe. Furthermore, since the toes of modern right and leftlasts are not symmetrical with respect to the longitudinal'median line,it becomes necessary in order that the lip of the innersole shall beproperly supported that the shape of the means for supporting the lip ofa right toe shall be the reverse of the shape of the means forsupporting the lip of a left toe. Therefore for the best results apressing member must have two pressing faces, one conforming to a righttoe and one conforming to a left toe.

It is the object of the present invention to provide a hold-down devicewhich will answer to the requirements of the trade conditions as aboveoutlined and preferably to provide a hold-down device having two of thechannel lip at the end of the toe and along one and preferably bothsides of the toe and having a substantially continuous.

or uninterrupted face forming an abutment for the inner face of the lipat the tip of the toe and along one and preferably both sides of the toeas and for the purpose stated. Preferably the abutting face for the lipwill extend substantially to or above the top of the lip to hold theupper portion of the lip against the pressure of the lasting plates thatare located on top of the overwiped upper.

A further feature of this invention is a hold-down device comprising anarm movable over a shoe supported by a lasting machine, and a pressingmember carried by said arm and having two pressing faces, one conformingto the toe portion of a right sole and the other conforming to the toeportion of a left sole, said member being adjustable relatively to thearm to make either pressing face operative or, in other 'words, to makethe said faces interchangeably operative.

A further feature of this invention is a hold-down device comprising apressing member and mountings therefor which member has formed on itsupper and lower faces respectively two pressing faces of the characterabove described for use with right and left shoes, said mountingspermitting detachment and inversion of the pressing member andre-attachment thereof to render operative either its pressing faces fora right shoe or its pressing faces for a left shoe. As I am advised itis new by this invention to provide a rightand left holddown devicewhich is invertible to render a pressing face that is on one side of itoperative for a right shoe and a pressing face that is on its oppositeside operative for use on a left shoe.

A further feature of this invention consists in the provision forlateral angular adjustment of such a pressing member as described aboutan axis located near its rear end for adapting each pressing face toform the described abutment, extending along the sides and particularlythe outer sides of the toe, for the channel lips of slightly differentcontours of right or left toes.

These and other features of the invention will app-ear more fully fromthe following detailed description when taken in connection with theaccompanying drawings and will then be definitely pointed out in theclaims.

Figure 1 is a perspective view of a hold- Ll( \\'1'1 1110l12111l8111embodying my invention and a portion of the toe head of a lastingmachine Figs. 2 detached show the and 3 show the hold-down device fromthe transverse carrier and pressing member adprsted respectively for aleft toe and for a right toe;said member fitting in each instanceagainst the inner face of the lip of the innersole;

Fig. l is a sectional view on the line 4c-'-l of Fig. 2;

Fig. 5 is a view of the lower face of a modified form of the hold-downfoot.

At A is shown the forward portion of a toe lasting head of thecommercial type of bed lasting machine, such, for example, as

that shown in U. S. LettersPatent to Brock No. 1,018,4l77, granted Feb.27, 1912. At B is shown a toe rest which sustains the toe portion of ashoe during the lasting operation. The operating mechanism for thehold-down is substantially similar to that disclosed and fully describedin the application of Keyes, Ser. No. 580,4100, to which reference maybe had for details not herein given. The post 2 is mounted for verticalmovement by means of a treadle not shown. The head 6 is mounted forrotation on the post 2 and supports a carrier 8 mounted to slide thereintransversely of the shoe and having friction means for holding it in anyposition of adjustment. The inner end of the support 8 carries a headedstud upon which is detachably held a finger or arm 10 by means of a slot12 provided for the purpose. of ashoe supported in the lasting machineand is provided with a depending stud 1% in the rear of which is a bolthole. A holddown plate or pressing member 16 is provided with a hole 18to fit the stud 1 1 and with a hole 20 which is located to aline withthe bolt hole in the arm and is countersunk on both sides. For holdingthe pressing member 16 securely to the arm 10 a stove bolt 22 isprovided, the head of which enters the countersunk hole 20 and the bodyof which passes through the hole in the arm 10 and is held by a nut 24,Fig. fl:- The pressing member 16 has a pressing face to engage down uponthe innersole and said member is contoured to provide for so clampingthe innersole at and adjacent to the base of the channel lip at the tipof the toe and along each side of the toe backwardly for a substantialdistance, as shown in Figs. 2 and 3. By so clamping the innersole to thelast at the base of the channel lip I successfully prevent very thin andflexible innersoles from crumpling or buckling up at the channel. Thepressing member also has an edge face 26 of sufficient height to extendsubstantially to, and it may be above, the top of the channel lip as inFig. 4: to present an abutment between which and the lasting plates 27the upper and toe stiffener 1 materials are compressed and molded intoan upstanding flange in position for sewing together in the weltattaching operation. The pressing member is contoured to pre- The arm 10extends toward the toe Hal sent, as shown in Fig. 2, said abutment 26133 in a continuous or uninterrupted line parallel to and in supportingcontact with the inner face of the channel lip at the tip of the toe andalong both sides of the toe back about as far as the upper materialswill be failed in wiping them over the concave edge of the toe of a leftshoe.

The upper side, Fig. 2, of the member 16 is adapted to serve as apressing face for a right shoe when said member is inverted as in Fig. 3and from the construction described it will be evident that by removingthe bolt 22 said member 16 may be slipped off of the stud 11, invertedand replaced upon the stud the other side up, in which position it maybe again secured to the arm by replacing the bolt and nut, 22, 24:-

By this construction is provided an invertible presser member having onits upper and lower sides respectively pressing faces shaped to fitdifi'erent shoes, as for example one face conforming to thetoe portionof a right shoe and the other face conforming to the toe portion of aleft shoe, and means for holding said member to its carrying arm 10 witheither pressing face disposed clownwardly in shoe engaging positionwhereby said faces may be made interchangeably operative.

In Fig. 5 the pressing member 16 is formed, as for example with twoholes 18, 15), to cooperate with the stud 1A in different positions ofadjustment whereby said pressing member may be made to conform toslightly different widths or to somewhat varying styles of shoes, thispressing member being preferably invertible for use with both rights andlefts.

The stud 14L on the arm 10 and the hole 18 Or 19 in theplate 16constitute what are herein termed coupling members which, with theassistance of thebolt and nut 22, 2a which retain the coupling membersin operative engagement, are adapted to secure the plate 16 to the arm10 with either side facing the sole of the shoe.
